Abstract
Description
Technical Field
[0001] This utility model relates to an electronic product, and more particularly to a stylus. Background Technology
[0002] With the rapid development of technology, many electronic devices have begun to adopt touch panels as their operating interface, such as smartphones and tablets, allowing users to operate them via touch and improving convenience. To make the operation process faster and more accurate, many users choose to use a stylus for input (such as writing or clicking).
[0003] Generally, styluses typically contain multiple interconnected components (such as circuit boards, circuits, sensors, or batteries). Therefore, when a stylus is impacted (e.g., dropped to the ground), the connections between these components (such as solder joints) are prone to breakage, which can severely impair the stylus's functionality. Utility Model Content
[0004] In view of the above, in one embodiment, a stylus is provided, comprising a hollow pen tube, an internal component, and a buffer. The internal component is disposed inside the hollow pen tube. The buffer is disposed inside the hollow pen tube and includes an elastic arm that directly or indirectly abuts against the internal component.
[0005] In summary, the stylus of this utility model embodiment, by setting a buffer inside the hollow pen tube, allows the elastic arm to buffer the components inside the hollow pen tube when the stylus is impacted (e.g., dropped to the ground), thereby preventing breakage at the joints (e.g., welded joints) of the components.

[0051] It should be noted that in the descriptions of the various embodiments, the terms "first," "second," and "third" are used to describe different elements, and these elements are not limited by such predicates. Furthermore, for ease of explanation and clarity, the thickness or dimensions of the elements in the drawings are exaggerated, omitted, or approximated for the understanding and reading of those skilled in the art. The dimensions of each element are not exactly their actual dimensions and are not intended to limit the implementation of this utility model; therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed in this utility model. The same reference numerals will be used to denote the same or similar elements in all drawings.
[0052] Figure 1 This is a perspective view of the first embodiment of the stylus of this utility model. Figure 2 This is an exploded perspective view of the first embodiment of the stylus of this utility model. Figure 3 This is a partial perspective view of the first embodiment of the stylus of this utility model. Figure 4 for Figure 1 Sectional view along line segment 4-4 Figure 5 for Figure 4 A magnified view of a specific area. For example... Figures 1 to 5 As shown, the stylus 1 of this utility model embodiment includes a hollow pen tube 10, an inner component 2, a tail cap 40, and a buffer component 45.
[0053] like Figure 1 and Figure 2 As shown, the hollow pen tube 10 has a pen tail end 11 and a pen tip end 12. The pen tail end 11 is used for assembling the tail cap 40, and the pen tip end 12 is used for assembling the pen tip 50. The pen tip 50 can be used to contact the touch interface of electronic products to provide users with more precise and sensitive operation. In this embodiment, a sensing module 51 is provided inside the hollow pen tube 10. The sensing module 51 is connected to the pen tip 50 and is used to receive signals from the pen tip 50. For example, the sensing module 51 can be a capacitive touch sensing module, an electromagnetic touch sensing module, an optical sensing module, or a pressure sensing module, etc.
[0054] like Figures 1 to 4 As shown, in this embodiment, the tail cap 40 has a groove 401 located outside the hollow pen tube 10. Thus, when the tail cap 40 is assembled onto the hollow pen tube 10 or plugged into other electronic devices (such as a notebook computer or charging port), the design of the groove 401 facilitates the user's assembly or disassembly.
[0055] like Figure 2 and Figure 4 As shown, the internal component 2 can be any element or structure within the hollow pen tube 10. In this embodiment, the internal component 2 includes a circuit board 20 and a power supply element 30, but this is not limited. In some embodiments, if the stylus 1 is not equipped with a power supply element 30, the internal component 2 may only include the circuit board 20, or the internal component 2 may be other components within the hollow pen tube 10. For example, the internal component 2 may also be other electronic components or partitions, supports, ribs, etc., inside the hollow pen tube 10.
[0056] like Figure 2 and Figure 4 As shown, the circuit board 20 is disposed inside the hollow pen tube 10. The circuit board 20 can be used to receive signals transmitted by the pen tip 50 or the sensing module 51 and process and convert them. In this embodiment, the circuit board 20 is located between the sensing module 51 and the pen tail end 11 of the hollow pen tube 10, and the circuit board 20 is electrically connected to the sensing module 51. For example, the circuit board 20 can be electrically connected to the sensing module 51 by soldering, so that the circuit board 20 can receive signals from the sensing module 51 or receive signals transmitted by the pen tip 50 through the sensing module 51.
[0057] like Figure 2 and Figure 4As shown, the power supply element 30 can be a rechargeable battery or a disposable battery. The power supply element 30 is disposed inside the hollow pen tube 10 and is used to provide power to the electronic components of the stylus 1 (such as the aforementioned circuit board 20 and sensing module 51). In this embodiment, the power supply element 30 is located between the circuit board 20 and the pen tail 11, and the power supply element 30 is electrically connected to and in contact with the circuit board 20. In a preferred embodiment, the power supply element 30 is a detachable component, which can be replaced and removed as needed.
[0058] like Figures 2 to 5 As shown, the tail cap 40 is disposed at the end 11 of the hollow pen tube 10. A buffer 45 is disposed inside the hollow pen tube 10 and is used to directly or indirectly abut against the aforementioned internal component 2. In this embodiment, the buffer 45 is located between the power supply element 30 and the tail cap 40. The buffer 45 includes an elastic arm 46, which can be directly or indirectly connected to the tail cap 40 and abut against the power supply element 30, so that the two ends of the power supply element 30 directly or indirectly abut against the circuit board 20 and the elastic arm 46, respectively.
[0059] Therefore, by providing a buffer 45 inside the hollow pen tube 10, the elastic arm 46 of the buffer 45 can cushion the internal component 2 inside the hollow pen tube 10 when the stylus 1 is impacted (e.g., dropped to the ground), thus preventing the internal component 2 from breaking. For example... Figures 2 to 5 As shown, the internal component 2 in this embodiment includes a circuit board 20 and a power supply element 30. By providing a buffer 45 between the power supply element 30 and the tail cover 40, and the elastic arm 46 of the buffer 45 is connected to the tail cover 40 and abuts against the power supply element 30, when the stylus 1 is impacted (e.g., dropped to the ground), the elastic arm 46 can simultaneously buffer the circuit board 20 and the power supply element 30 inside the hollow pen tube 10, so as to prevent the connection between the circuit board 20 and other components (e.g., the solder joint between the aforementioned circuit board 20 and the sensing module 51) from breaking, and at the same time, it can also prevent the power supply element 30 from being disconnected from other components, thereby improving the service life of the stylus 1.
[0060] In addition, such as Figures 2 to 5 As shown, in this embodiment, the power supply component 30 is located between the circuit board 20 and the pen tail 11, and the heavier power supply component 30 is closer to the pen tail 11, causing the center of gravity of the stylus 1 to be biased towards the pen tail 11. Therefore, when the stylus 1 is dropped, the pen tail 11 usually hits the ground first. To address this, this embodiment of the invention provides a better cushioning effect by placing the buffer 45 near the pen tail 11, thereby effectively preventing the stylus 1 from breaking.
[0061] The structure of the buffer 45 and the connection between the buffer 45 and the tail cap 40 can have various embodiments, which are described below with reference to the drawings.
[0062] In some embodiments, the elastic arm 46 of the buffer 45 may be integrally connected to the tail cap 40, or the elastic arm 46 of the buffer 45 may also be assembled to the tail cap 40. For example Figure 4 and Figure 5 As shown, in this embodiment, the tail cap 40 includes a cover body 41, and the buffer member 45 includes a connecting plate 47. The connecting plate 47 is integrally connected between the elastic arm 46 and the cover body 41. That is, the connecting plate 47, the elastic arm 46, and the cover body 41 are integrally formed, which can improve the overall structural strength of the tail cap 40, and the tail cap 40 and the buffer member 45 can be assembled more easily. However, the above embodiment is only an example. In other embodiments, the elastic arm 46 can also be directly connected to the tail cap 40 without other components (such as the aforementioned connecting plate 47), depending on the actual product requirements.
[0063] In some embodiments, the elastic arm 46 of the buffer 45 can be a straight elastic arm, an arc elastic arm, an L-shaped elastic arm, an S-shaped elastic arm, or a serpentine elastic arm, etc., that is, the shape of the elastic arm 46 is not limited. For example Figure 4 and Figure 5 As shown, in this embodiment, the elastic arm 46 includes a first elastic arm 461, a second elastic arm 462, a third elastic arm 463, and a plurality of connecting arms 465a, 465b, 465c. The first elastic arm 461 abuts against the power supply element 30. The second elastic arm 462 and the third elastic arm 463 are located between the first elastic arm 461 and the cover 41, and the first elastic arm 461, the second elastic arm 462, and the third elastic arm 463 are arranged parallel to each other. The connecting arms 465a, 465b, 465c... 65c is perpendicular to the first elastic arm 461. One connecting arm 465a has its two ends connected to the ends of the first elastic arm 461 and the second elastic arm 462, respectively. Another connecting arm 465b has its two ends connected to the ends of the second elastic arm 462 and the third elastic arm 463, respectively. Another connecting arm 465c has its two ends connected to the end of the third elastic arm 463 and the connecting plate 47, respectively. This makes the elastic arm 46 serpentine in shape and connected to the tail cap 40 via the connecting plate 47. In other embodiments, the elastic arm 46 of the buffer member 45 can also be directly connected to the tail cap 40 without passing through other components (such as the aforementioned connecting plate 47). Furthermore, the connecting arms 465a, 465b, and 465c are not limited to being perpendicular to the first elastic arm 461.
[0064] Preferably, in Figure 4 and Figure 5In the middle, the first spring arm 461, the second spring arm 462 and the third spring arm 463 have a first end and a second end respectively. One connecting arm 465a is connected to the first end of the first spring arm 461 and the first end of the second spring arm 462. Another connecting arm 465b is connected to the second end of the second spring arm 462 and the second end of the third spring arm 463. Yet another connecting arm 465c is connected between the first end of the third spring arm 463 and the cover 41. The side of the first spring arm 461 abuts against the power supply element 30.
[0065] However, the above embodiments are merely examples. In other embodiments, the elastic arm 46 may be formed by alternating connections of at least one spring arm and at least one connecting arm. The number, shape, and connection method of the spring arms and connecting arms of the elastic arm 46 may have various other combinations. For example, the elastic arm 46 may only include the first spring arm 461 and the connecting arm 465a to form an L-shaped spring arm; or the elastic arm 46 may only include the first spring arm 461, the second spring arm 462, and the two connecting arms 465a and 465b to form a C-shaped spring arm; or the elastic arm 46 may only include the first spring arm 461, the second spring arm 462, and the third spring arm 463, and the first spring arm 461, the second spring arm 462, and the third spring arm 463 are connected to each other. For example, the first spring arm 461, the second spring arm 462, and the third spring arm 463 may each be an arc-shaped spring arm and form an S-shaped spring arm after being connected, thus eliminating the need to separately provide the connecting arms 465a, 465b, and 465c.
[0066] Additionally, the elastic arm 46 of the buffer 45 may have at least one protrusion 466, which abuts against the inner component 2, such as... Figure 4 and Figure 5 As shown, the elastic arm 46 abuts against the power supply element 30 with protrusions 466, which can reduce the contact friction area between the elastic arm 46 and the power supply element 30. In this embodiment, there are multiple protrusions 466 and they are located on the surface of the first elastic arm 461 of the elastic arm 46 facing the power supply element 30.
[0067] like Figure 4 and Figure 5As shown, in this embodiment, the tail cap 40 further includes a tail tube 42, which is connected between the pen tail end 11 of the hollow pen tube 10 and the cap body 41. The tail tube 42 includes an inner tube 421, an outer tube 422 and a connecting section 423. In a preferred embodiment, the connecting section 423 may be, but is not limited to, annular. The connecting section 423 is integrally connected between the inner tube 421 and the outer tube 422. The width of the inner tube 421 is smaller than the width of the outer tube 422. The inner tube 421 is located inside the hollow pen tube 10, and the outer tube 422 is located outside the hollow pen tube 10. Furthermore, the tail tube 42 has an axial direction A and a radial direction R. The axial direction A is the extension direction of the central axis of the tail tube 42. In this embodiment, the axial direction A of the tail tube 42 is the same as the extension direction of the hollow pen tube 10, and the radial direction R of the tail tube 42 is perpendicular to the axial direction A. The thickness T1 of the connecting section 423 of the tail tube 42 in the axial direction A is greater than the wall thickness T2 of the inner tube 421 in the radial direction R. By increasing the thickness of the connecting section 423 in the axial direction A, the overall structural strength of the tail tube 42 can be strengthened, thereby preventing the tail cap 40 from easily breaking under stress. In addition, it can also effectively prevent the tail tube 42 from breaking at the connection between the inner tube 421 and the outer tube 422 (e.g., the connecting section 423) under stress, thereby further improving the service life of the tail cap 40.
[0068] For example Figures 3 to 5 As shown, the buffer 45 can be located inside the tail tube 42 of the tail cap 40 and connected to the cap body 41. The tail tube 42 has at least one limiting groove 425. A portion of the buffer 45 is located in the limiting groove 425, allowing the buffer 45 to be limited and prevent displacement. Furthermore, the connection between the buffer 45 and the tail tube 42 further strengthens the overall structural strength of the tail cap 40, preventing it from easily breaking under stress. In addition, during assembly, the buffer 45 can be guided by the limiting groove 425 of the tail tube 42 and installed inside the hollow pen tube 10, improving assembly convenience. In this embodiment, there are two limiting grooves 425, located on opposite sides of the tail tube 42, with the elastic arm 46 of the buffer 45 located on both sides within the two limiting grooves 425.
[0069] Figure 6 This is a partial perspective view of the second embodiment of the stylus of this utility model. Figure 7 This is a cross-sectional view of the second embodiment of the stylus of this utility model. Figure 6 and Figure 7As shown, the difference between this embodiment and the first embodiment described above is at least that the elastic arm 46 of the buffer 45a in this embodiment is assembled to the tail cover 40 rather than being integrally connected to the tail cover 40. For example, the buffer 45a can be assembled and fixed to the tail cover 40 by means of adhesion, snap-fit, or locking. For example, in this embodiment, the cover body 41 of the tail cover 40 has a slot 44, the elastic arm 46 of the buffer 45a extends from one end of the connecting plate 47, and the other end of the connecting plate 47 is assembled into the slot 44 of the cover body 41, so that the elastic arm 46 is assembled to the cover body 41 of the tail cover 40 via the connecting plate 47. In other embodiments, the elastic arm 46 may also be partially located in the slot 44 of the cover body 41 to be assembled to the cover body 41, thus omitting the setting of the connecting plate 47.
[0070] Figure 8 This is a partial exploded perspective view of the third embodiment of the stylus of this utility model. Figure 9 This is a cross-sectional view of the third embodiment of the stylus of this utility model. Figure 8 and Figure 9 As shown, the difference between this embodiment and the first embodiment described above is at least that the buffer 45b in this embodiment includes multiple elastic arms 46 (here, two elastic arms 46, but more than two are also possible), and each elastic arm 46 is a straight elastic arm. The multiple elastic arms 46 are spaced apart from each other, and one end of each elastic arm 46 is integrally connected to the connecting plate 47. The other end of each elastic arm 46 has a protrusion 466 and abuts against the power supply element 30 through the protrusion 466. Thus, the multiple elastic arms 46 can abut against different areas of the power supply element 30 respectively to provide a better buffering effect. In other embodiments, each elastic arm 46 of the buffer 45b can also be directly connected to the cover 41, thus omitting the setting of the connecting plate 47.
[0071] Figure 10 This is a partial perspective view of the fourth embodiment of the stylus of this utility model. Figure 11 This is a cross-sectional view of the fourth embodiment of the stylus of this utility model. Figure 10 and Figure 11As shown, the difference between this embodiment and the first embodiment described above is at least that the number of buffers 45c in this embodiment is multiple (in this case, there are two buffers 45c), and the two buffers 45c are spaced apart along the wall of the inner tube 421. Each buffer 45c includes at least two extension arms 48 (in this case, there are two extension arms 48, but this is not a limitation) and an elastic arm 46. The multiple extension arms 48 are spaced apart from each other. Each extension arm 48 has a connecting end 481 and an extension end 482. The connecting end 481 is connected to the inner tube 421 of the tail tube 42 of the tail cap 40, and the extension end 482 is adjacent to the power supply element 30. The elastic arm 46 of each buffer 45c can be perpendicular to each extension arm 48, and the two ends of each elastic arm 46 are respectively connected to the extension ends 482 of the two extension arms 48. Each elastic arm 46 has a protrusion 466 and abuts against the power supply element 30 through the protrusion 466, thereby achieving the above-mentioned buffering effect.
[0072] For example Figure 10 and Figure 11 As shown, in this embodiment, the elastic arm 46 of each buffer 45c is arc-shaped, and the curvature of each elastic arm 46 corresponds to the curvature of the inner tube 421, so as to avoid affecting the assembly of the inner tube 421 with other components.
[0073] In some embodiments, the stylus 1 may also include multiple buffers, with some buffers connected to the cover 41 of the tail cap 40 and others disposed on the tail tube 42 of the tail cap 40. For example Figure 12 The image shown is a cross-sectional view of the fifth embodiment of the stylus of this utility model. In this embodiment, the stylus 1 includes the above-described... Figure 5 Buffer 45 in the embodiment and Figure 10 As described above, the multiple buffers 45c in the embodiment are connected to the cover 41 of the tail cover 40 and abut against the power supply element 30. The multiple buffers 45c are disposed at one end of the inner tube 421 of the tail tube 42 and abut against the power supply element 30, so that the multiple buffers 45, 45c can abut against different areas of the power supply element 30 respectively to provide a better buffering effect.
[0074] Although the technical content of this utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit this utility model. Any modifications and refinements made by those skilled in the art without departing from the spirit of this utility model should be included within the scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the appended claims.
